Sunlu 8-color 0.25kg PETG packs are on sale at Amazon from the normal $40-50 price and are further eligible for 5-10% S&S discount.

At $15-16 per kg, this isn't the cheapest per kg price but if you want color variety it's a decent deal since you avoid having to buy full 1kg rolls of colors that you won't use much of.


$29.87 with S&S for 'Macaron' color set (Sunny Orange+Lemon Yellow+Mint Green+Sky Blue+Sakura Pink+White+Grey+Black)

https://www.amazon.com/dp/B0BN657YY3


$32.29 with S&S for standard multicolor set (Black+White+Blue+Green+Red+Orange+Yellow+Pink)

Yes, sealed filament can sit for a long while. Once you open a package, a filament would start absorbing moisture from the air, which leads to stringy prints - see here https://www.thingiverse.com/thing:2219103. How fast / how bad depends on your climate and the type of filament.

That said, you might eventually want to get a few things:

1. Filament dryer. This would allow to re-dry filament however many times you need, making spools last basically indefinite. While you can get a commercial one, you can build a much better one from a food dehydrator and some 3d printed walls like this one https://www.thingiverse.com/thing:4754084

2. Get a box with a sealing lid and use it for storing filaments. Like this one sold at target/walmart for about $10 (there is ton of mods that you can do to the box): https://www.thingiverse.com/thing:1720315

3. Get a gallon of silica gel and throw it in the box from step 2. The gel would help to absorb the moisture. And when it's too wet - use the dryer from step 1 to make it dry again.
I really like these quarter-kg packs. Sometimes you need a little bit of a color but are never going to use an entire KG of them. Yellow, pink, I have basically no use for personally but every once in a while I could use them, and end up not doing the print since I don't have them.

I got a quarter-kg of silk blends a few months back and they're still mostly unused but they've definitely been ideal for a couple designs. Wish more manufacturers did this.

S&S doesn't seem to be working for either of these. It just takes me to the normal ordering page with delivery this week and no S&S discount.

If I keep them sealed should they last a while? I am very slow on getting my printer setup so wondering if I should bother grabbing filament deals

That's weird, it worked for 10% for me when I first ordered. Now I can't get it to show up at checkout but if I use the checkbox for S&S on the checkout page I can still get it to give me 5% off (assuming you're at the 5 item tier already). If you're at 5 items it's better than nothing. Maybe you can chat with support and get them to credit you the difference.

Are these any good? I bought a kg of generic PETG and it warps and almost always detaches from the bed no matter what I do. I've tried brim, increasing bed/hot end temp, decreasing bed/hot end temp, improvised bag enclosure, glue, changing print speed. Nothing works. I'm guessing it's the filament so I want to know if this will be as bad and a waste of money.

I haven't bought the 250g bundles before but the 1 kg blue Sunlu PETG I bought printed fine after tuning the settings (235C, 75C bed, glue stick on glass bed, draft wall for larger items).

S&S is definitely broken but before checking out you could still sign up. You end up getting it faster but only saving 5%. Better than nothing.

Dry it out (dehydrator, sunlu dryer, etc) maybe look into a PEI sheet to make sure it adheres properly.

They will be good for a long time sealed, depending on ambient moisture and the brand, they are fine for a while unsealed. Most of my old stuff is fine and it just sits in my 200 year old basement that only has 1 dehumidifier on the the other side of the basement set for 60% humidity.
